习惯形成、信息鸿沟与异质福利--基于中国地区层面居民信息消费数据的数值模拟分析

本文尝试将消费习惯引入信息消费增速提升的福利效应模型，并以此模型为基础，运用1992～2012年中国城镇居民家庭信息消费数据，测算了信息消费增速提升给中国不同区域城镇居民带来的差异福利影响。研究发现：第一，内部习惯特征对中国城镇居民信息消费的福利效应具有显著影响。引入习惯特征后，信息消费增速提升1%相当于在其未来无限生命期界内每年补贴0.27%-26.05%信息消费产品或服务；第二，无论是同质性偏好还是异质性偏好假设，四大板块中的东北和中西部地区城镇居民信息消费的福利效应均高于东部地区，区域间信息鸿沟转化为福利差异。因此，在稳步推进收入分配和社会保障体制改革的同时，应当加大对中西部地区信息基础设施政策支持力度。

Habit Formation,Information Gap and Heterogeneous Welfare--Numerical Simulation Analysis of the Region Level of Chinese Residents Based on Information Consumption Data

This paper attempts to build a information consumption welfare effects model which introduces the habit forming factor, and using China＇s 26 provinces （autonomous regions） urban households＇ consumption data from 1992 to 2012, estimate and compare the social welfare effects of information consumption. The Study found that： Firstly, internal habits characteristic have a significant impact to china urban residents＇ information consumption welfare effects. After introducing the habit information features, information consumption growth rate improve by 1%, equivalent to subsidy consumer 0.27% to 26.05% information products or services every year in their future unlimited lifetime. Secondly, whether homogeneous or heterogeneous preferences preference hypothesis, the welfare effects of Northeast and Midwest regions urban residents information consumption higher than the eastern region, inter-regional information divide into consumer welfare differences. Thus, government should steadily advance income distribution and social security system reform, at the same time should increase central and western regions information infrastructure policy support.
